April 8, 2015 - Square Logo
The square logo is mostly for use online. It should work big and small. If you were to use it on Facebook, people visiting your page would see it in a larger format. But when you comment, it would be so small that type can be hard to read. I've put together a few versions in both small and large versions for your review.

As you are a Red Angus ranch, it only seems appropriate to use red for a color. As for color #2, black works well with red -and- it is a standard ink when you go run ads or print business cards. I left a couple logos that have two or more colors (no black) in for comparison.
